MILK-BOTTLE-LOCKING DEVICE.

Specification of Letters Patent.

Patented Aug. 8, 1916.

Application filed November 20, 1915. Serial No. 62,578.

T 0 all whom it may concern Be it known that I, JOHN G. R. SCHU- MANN, asubject of the Emperor of Germany, residing at Elizabeth, in the countyof Union and State of New Jersey, have invented certain new and usefulImprovements in Milk-Bottle-Locking Devices; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to new and useful improvements in milk bottlelocking devices and the principal object of the invention is to providea device which will prevent milk bottles from being stolen from thedoorstep after having been placed there by the milk.

man.

Another object of the invention is to provide a locking device capableof preventing the bottle from being removed except when released fromthe inside of the door.

A further object of the invention is to provide a device which may bereadily attached to doors of the ordinary construction withoutnecessitating the alteration thereof.

WVith these and other objects in view the invention consists in thenovel combination and arrangement of parts which will be fully set forthin the following specification and accompanying drawings, in whichFigure 1 is a sectional view through a door illustrating this deviceapplied thereto. Fig. 2 is a horizontal sectional view showing thedevice applied to the door. Fig. 3 is a fragmentary elevation of thedoor showing the attachment in place, and Fig. 4 is a fragmentary frontelevation of the door showing the front plate of the device.

Referring now to the drawing by characters of reference, the numeral 1designates as an entirety the front plate best illustrated in Fig. 4comprising a body 2 having chamfered edge 3, a central opening 4 isformed in the plate and has communicating therewith the transverselyextending slot 5. The opposite ends of the slot 5 extend beyond theopening 4 and form chambers for the reception of the lugs which will bemore fully hereinafter described. Extending through the plate near eachend are the screws 6 by means of which the same is held in place on thedoor.

Secured to the rear of the door is a latch plate 7, provided at one endwith the up.

turned flange 8 through which the pin 9 extends. A suitable latchhousing .10 is secured to the plate and slidable therein is the latch11, which is formed with the axial bore 12. The pin 9 extends into thelatch housing and projects in the bore 12 and forms a guide for thelatch as clearly illustrated in Fig. 2. The forward end of the latch 11is formed with the ratchet engaging member 13 and a suitable spring 14:is positioned between the end wall of the housing 10 and the rear faceof the latch 11. The latch plate 7 is formed with a suitable opening 15,which is positioned at one end of the housing 10 and in alinement withthe ratchet engaging portion 13 so that when said portion is forcedoutwardly as shown in Figs. 2 and 3, the same will partially overlie theopening so as to engage the member which is passed therethrough.

The plates 1 and 7 are secured to the door in such a position as toallow their openings 4 and 15 respectively to aline and also to alinewith a suitable opening drilled in the door previously to the securingof the plates in place.

The bottle holder is designated generally 7 by the numeral 16 andcomprises the stem 17 provided with a plurality of ratchet teeth 18 andthis stem is provided with the forward semi-cylindrical projection 19 towhich is pivotally secured as at 20, the semicircular neck encirclingmember 21. A suitable lug 22 extends laterally from the semicylindricalextension 19 and pivotally connected as at 22 to the outer end of thesemicircular neck encircling member 21 is the cooperating semi-circularneck encircling member 23 to which is pivotally secured as at 2%, thesemi-cylindrical member 25, which cooperates with the semi-cylindricalextension 19 in forming a continuation of the stem 17. Thissemi-cylindrical member 25 is provided with a lug 26, which is identicalin con struction with the lug 22 and has formed near its free end anopening 27 through which the pin 28 carried by the semi-cylindricalextension 19 extends.

It will be apparent from the foregoing that in use the bottle is placedbetween the ring encircling members 21 and 23 and the same are thenswung closed on their pivot 22 and in such position that thesemi-cylin-.

the end of the stem 17. The stem 17 is then passed through the openings4 and 15 in such a way that the ratchet teeth 18 will be engaged by thetooth engaging member 13 and upon forcing the shank inwardly as far asit will go, it will be evident that the lugs 22 and 26 will lie in theslot 5 and thereby prevent the device from being twisted by invertingthe bottle. It will thus be seen that the bottle cannot be removed fromthe outside of the door and may be easily and quickly removed byreleasing the latch on the inside of the door.

While in the foregoing there has been shown and described the preferredembodiment of this invention, it is to be understood that such changesmay be made in the combination and arrangement of parts as will fallwithin the spirit and scope of the appended claim.

What is claimed is The combination with a door having an opening nearits bottom, a ratchet plate secured on the inside of the door, saidratchet plate being formed with an opening alining with the opening inthe door, a front plate on the outside of the door having a centralopening therein alining with the opening in the door, the front platealso having a transverse slot extending therethrough and communicatingwith the opening, and a ratchet on the ratchet plate, of a stem arrangedto extend through the openings, the teeth on the stem arranged to beengaged by the ratchet, a semi-cylindrical extension on the forward endof the stem, a semi-circular neck engaging member pivoted to the forwardend of the semi-cylindrical extension, a cooperatingsemi-circular neckengaging member pivoted to the forward end of the first mentioned neckengaging member, a semi-cylindrical member pivoted to the free end ofthe last mentioned semi-circular member, the semi-cylindrical memberbeing of a size equal to the semicylindrical extension, and lugs on theextension of'the semi-cylindrical member engaging in the slot in thefront plate to lock the whole against turning.

In testimony whereof I aflix my signature in presence of two witnesses.

JOHN G. R. SCHUMANN.
